Second part of patches submitted in the v3.
This series adds a subset of single precision and
double precision instructions using
set_floatx80_rounding_precision() to round the result.
For some other instructions, we introduce a new
function, floatx80_round(), to round them manually.
It also adds instructions fsglmul, fsgldiv,
fmovecr and fscc (since v3, use tcg_gen_setcond())
fmovem manages static and dynamic register list,
all the code has been moved to an helper.
v4:
Update floatx80_round() comment (and add Aurélien's R-b)
Add a comment for undefined fmovecr offsets
update gen_fcc_cond() with more fixes from Richard
v3:
Remove extra space in fmovem patch
truncate operands of fsglmul and fslgdiv
update gen_fcc_cond() as suggested by Richard
fmoverc: use opmode instead of rom_offset,
define and free the tcg constant
v2:
Fix gen_fcc_cond(): g[12] mark global variables,
not variables to free.
add 2 patches to compute trigonometric functions
and fmod
use floatx80_round() to compute fsglmul and fsgldiv
split fmovem helper into 6 helpers
